Review comment:
We need to closely understand the this function:
https://github.com/apache/systemml/blob/faec15810e18fc497e950b830811a919f5aa5c5f/scripts/builtin/kmeans.dml#L46
Think about the inputs required and initialize the required arguments.
We can take already implemented functions as examples.
This task is tough and iterative, copy-paste solutions are not available.
Some people spend whole days to find the correct combinations, though. 🙂
